What season is best for rose cutting to ensure survival?
Do you know these? This is an introduction to the related knowledge of green plants and flowers about the best season for rose cutting and the method for fast root growth of roses. Let's share the detailed content next.
Roses are deciduous shrubs of the Rosaceae family, Rosaceae, with a vine-like or creeping growth habit. They have a rich variety of flower colors and strong fragrance, blooming throughout the four seasons with high ornamental value. The flower colors range from red, pink, yellow, white, orange, purple, variegated, original color, to bicolor on the front and back, and are very diverse. Roses are known as the queens of flowers, with strong adaptability, cold and drought resistance, and easy to grow, making them a favorite ornamental plant for urban and rural people. Roses are also known as ever-blooming flowers or four-season roses because they bloom all year round. Roses are one of the most popular flowers among home gardening enthusiasts, widely cultivated in various regions, especially indoor potted roses. The propagation of roses through cutting is relatively easy, with low production costs for the flower seedlings and suitable for mass production. In what season should roses be cut? Roses can be cut all year round, with the highest survival rate in spring cuttings.
Spring Cuttings: Spring cuttings usually start from mid to late April and end by the end of May. Due to the warm climate and relatively high humidity during this season, the cut surface can heal in about 20 days, and roots can grow in about 25 days. With careful management, the success rate of cutting can exceed 95%. The cuttings can be transplanted into pots after a month.
Summer Cuttings: The cutting and method are the same as in spring. The main task in summer is to provide good shading and keep the bed soil moist, maintaining 95% relative humidity of the air. However, the cutting bed should not be too wet, and the cuttings should be sprayed at 9-10 AM and 3-4 PM in the afternoon.
Autumn Cuttings: Autumn cuttings start from the end of August and end by the end of October. Due to the gradually decreasing temperature and large temperature differences between day and night, the healing of the cuttings and the root growth rate are slower than in spring.
Winter Cuttings: With low temperatures in winter, winter cuttings are usually done in greenhouses, plastic greenhouses, or small arch sheds covered with plastic mulch. The main management task is to keep the temperature and humidity. To promote root growth, the cuttings can be treated with indole butyric acid or indole acetic acid for 10-30 seconds, or girdled before cutting.
Are there any precautions for rose cutting?
First, pay attention to controlling temperature and humidity during rose cutting, generally requiring temperatures between 25-30°C. The air humidity should be above 80%, and the soil moisture should not be too high. It is sufficient if the soil can form a ball when pinched in hand and crumble when released. Too much soil moisture can cause the base of the cutting to rot.
Second, the selection of cuttings, different rose varieties have different flower and stem sizes. To make the roses grow short and strong, it is first necessary to choose large-flowered varieties. The cuttings should be taken from healthy, disease-free mother plants, choosing thick and strong stems for cutting propagation to ensure sturdy plant growth.
Third, the cutting density should not be too dense, and it is best to collect cuttings, plant, water, and shade simultaneously. A slightly sparse cutting density, with a spacing of about 9 cm between plants, results in sturdier plants.
Fourth, the cutting bed should be filled with 20 cm of coarse sand that has been sieved and cleaned with water. After cutting, water thoroughly and set up a shade shelter.
Fifth, after the rose cuttings have rooted, they should be checked promptly. If the roots of the rose cuttings are about 5 cm long and the color changes from white to brown, they should be transplanted immediately. Otherwise, if the time is too long, the limited nutrients in the stems will not be supplied, and the stems will wither.
